Where is the glioma located?
Glioma is a common type of tumor originating in the brain. About 33 percent of all brain tumors are gliomas, which originate in the glial cells that surround and support neurons in the brain, including astrocytes, oligodendrocytes and ependymal cells.
What is intra axial lesion?
Brain tumors that are rooted in the brain Parenchyma are referred to as intra-axial. If the origin of the tumor is outside of the brain (or it is due to metastasis), it is called extra-axial (4, 5).
What is an extra-axial tumor?
Abstract. Extra-axial tumors are lesions, neoplastic and not, which are external to the brain parenchyma and can originate in the skull, meninges, cranial nerves, and brain appendages such as the pituitary gland.
Are glioma tumors cancerous?
Gliomas can be not cancer (benign) or cancer (malignant). They make up about 3 in 10 of all tumors that start in the brain. If a brain tumor isn’t cancer, it may still need to be treated. This is because even small tumors can press on normal brain tissue and cause problems.
What is intra-axial and extra-axial brain tumors?
Brain tumors can be intra-axial or extra-axial. The intra-axial tumors are located within brain parenchyma and arise from the brain cells, while the extra-axial tumors are located outside brain parenchyma and arise from structures lining the brain or surrounding it.
What is a calcified extra-axial mass?
Extra-axial brain stones comprise tumors and exaggerated physiological calcifications. Intra-axial calcifications can be classified as vascular, neoplastic, congenital, infectious, and endocrine/metabolic etiologies. Vascular causes represent a substantial portion of intra-axial lesions.
What does Extraaxial mean?
Extra-axial is a descriptive term to denote lesions that are external to the brain parenchyma, in contrast to intra-axial which describes lesions within the brain substance.
